Density Approximation of Affine Jump Diffusions via Closed-Form Moment Matching
Yan-Feng Wu, Jian-Qiang Hu
We develop a recursive approach for deriving closed-form solutions to both conditional and unconditional moments of affine jump diffusions with state-independent jump intensities.…

Method of Moments Estimation for Affine Stochastic Volatility Models
Yan-Feng Wu, Xiangyu Yang, Jian-Qiang Hu
We develop moment estimators for the parameters of affine stochastic volatility models. We first address the challenge of calculating moments for the models by introducing a recurs…
